I use WINme. I run MSCONFIG, then Selective Startup, then Process System.ini.
This shuts down all non-essential things in the background and I get 40+ fps
with N4. This is with 50 percent world detail, 43 cars, 12 look ahead and 3 in
back.
But I installed XP and found that if I ran MSCONFIG, etc., then I ended up with
no sound and no controller. So I had to run in a normal XP environment and I
got 20-25 fps. Enditall didn't make that much of a difference, either.
I wish I could use XP, but it just totally wrecks N4. Same is true for GPL.
Sincerely, James
